How To Make Crab Melts

This is one of those easy recipes that is very similar to any tuna melt recipe but instead of tuna you’re using decadent crab meat!

One thing I’ve learned when it comes to recipes using crab meat is that you really don’t want to overwhelm the taste of the delicate crab by adding too many ingredients.

As a matter of fact, I consider it an art form to use crab meat in a recipe and actually enhance the taste of the crab meat vs. covering it up!

So when I was developing this crab sandwich recipe, I kept this in the forefront of my mind!

In addition, while we’re on the subject of crab recipes, you have to try out my other crab recipes, like my:

Sandwich ingredients

Step-by-Step Instructions

Step 1: Mix Mayo and Lemon Juice & Add in Crab Meat

First, in a medium bowl mix your mayonnaise and lemon juice until well combined.

Then add your lump crab meat and mix well.

Step 2: Add Old Bay Seasoning, Celery, Red Onion, & Parsley

Step 3: Brush Melted Butter on Bread Slices and Top with Crab Meat Mixture

At this point, using a basting brush, generously brush one side of your bottom slices of bread with melted butter and place them, buttered face down, onto a broiling pan.

Then top each slice of bread with half of your crab mixture.

Step 4: Top Each Sandwich with Cheese & Buttered Bread Slices

Now, add a slice of cheese to each sandwich and then top with bread slices that have been brushed with butter, with the buttered side up.

Note: I like to place the cheese so that it’s hanging over the edge of the bread a little bit.

That way when it bakes in the oven, you get that melty cheese effect. Mmm!

How To Cook Crab Melts

Finally, place your crab melts on a cookie sheet or broiler pan in a preheated 400 degrees Fahrenheit oven and bake for 5 minutes.

Then carefully flip your crab melts and bake for another 3 to 4 minutes.

After that, turn your oven on broil and let the tops toast for another 1 to 2 minutes.

It’s very important that you keep a close eye on your sandwiches while they are broiling because they can go from toasty to burned in a split second.

What Goes With Crab Melts

A great addition to your crab melt is to add tomato slices.

Personally, I don’t like to heat up my tomato in the oven with the crab melts because it can make them a little bit soggy and less crispy.

So, adding the tomatoes after the sandwich is heated up is my preference.

In addition, because crab meat is already rich, these melts are very filling, so you might not even need a side to go with them.

However, it’s always a nice idea to include a light side such as fruit or plain potato chips.

You don’t want to include flavored potato chips because that will compete with the star of the show – your crab melts!

Tips, Tricks, & Substitutions

  • Do not use salt in this recipe! The Old Bay Seasoning has plenty of salt in it!
  • Get good quality lump crab meat. 
  • It’s really important to measure your ingredients because if you add too much of them, they will take over the flavor of the crab meat.
  • To give it a little more of a kick, add a few drops of hot sauce.
  • Other ingredient substitutions:
    • Green onions instead of red onions
    • Swiss cheese instead of cheddar cheese
    • For a more budget friendly option, use imitation crab
    • Best bread options:
      • Tuscan garlic bread
      • English muffins – make these melts open faced on each muffin half
      • French bread
      • Ciabatta roll
      • Sourdough bread

Can You Reheat A Crab Melt

Yes, you can definitely reheat your crab melt.

As a matter of fact, I made these crabby melts earlier in the day and then reheated them for my husband and son for dinner.

I placed them into the oven at 350 degrees Fahrenheit for about 10 minutes, just enough to heat them through and to see the cheese melting.

Can You Refrigerate Crab Melts

Yes, I placed my crab melts in ziploc baggies and refrigerated them for about 5 hours before I reheated them for dinner.

They reheated beautifully!

And, by all means, if you have leftovers, save what’s left and refrigerate them for 1 to 2 days. 

However, if your family is like mine, your crab melts will be eaten up in no time.

As a matter of fact, I asked my husband if he had any suggestions for my recipe and he said ‘Make me more!’

I’d say that’s a great seal of approval!
